Raymon Hill has released a new extension which records which (third-party) websites you have engaged when surfing the internet. After installation when you click the UBO-Scope ICON it informs you about the third-party exposure. When you click the icon, you get the default tile unfiltered (I guess alphabetic) view. When you click on the corner left, you can switch from tile to list view. Clicking on the filter icon on the right sorts the websites on exposure percentage (from high to low). In the options screen you change the number of days UBO-Scope records third-part exposure. You can also export the list to build your own (anti)tracking lists for UBlock, AdGuard or AdBlock.. These numbers are illustrative when disabling advertisement and tracking protection and clicking on a few major news websites . IMPORTANT NOTICE: UBO-Scope shows EXPOSURE not TRACKING. Many major websites have committed themselves to the self regulation FAIR USE/NO-TRACKING policy. Problem is when you bother to read the details of the self regulating policies of the advertising business, your definition of FAIR USE/NO TRACKING may differ from their FAIR USE/NO TRACKING definition. POSSIBLE USE: When you try out new filterlists you can get an idea of the effectiveness of this new filterlist. The reverse applies also,when you remove a filterlist, you can see how much the exposure increases. It would be handy when the optios screen had a RESET button. When you click on a website it shows detailed info in the header. It also informs you about the nature of that website (e..g. Advertising or Content).
